I have a user who is losing connectivity from their Outlook 2010 client (Windows 7 PC) to the Exchange 2007 server (Server 2008) every couple of days. It happens at random, with no pattern. When this happens, Outlooks shows connected, but clicking send/receive will not bring in any e-mails. Sending e-mails from Outlook DOES work. This is the only user having a problem on our network. I have tried removing all add-ins, repairing the Outlook installation, removing and re-installing Outlook, and so far those have not helped. Also, nothing shows in Event Viewer.Two things that I have tried that do help (sort of) is removing and re-joining the machine to the domain, and removing the mail profile in control panel and re-adding it. After doing this, the user is able to send e-mail for a couple of days, and then eventually the same situation will occur. Recently I was also informed that every once in a while, the connection will work. Usually one or two days out of the week, but other than that, the user is unable to send. Anyone have any suggestions?
